The purpose ?~ .the meeting w~sto acquaint us with the physical facIl:tI.es at the ~xpen-ment station and to seek our Opll11OnSrelative toinitiating a postive research program in the field offine tudgrass. In addition to Mr. Kemmer.er, Dr.Birkeland head of the Department of Horticulture,was pres~nt; Dr. Wienard, Professor of Floriculturewho has been active in turf work for many year ;Mr. Miller, the re ident at the experiment station;and Mr. Jack Butler, who has been employed to workin turfgrass research full time. .. ..

According to Dr. Birkeland, the U ruversity of IllInOISis prepared to expend during the next year between$20,000 and $30,000 f~r work in turf. H~~ever, avery unique situation eXI ts. Fund and ~u~IIfIed per-sonnel are available (although not unlimited}, .butthey have no pecific research projects: . We have failedto indicate to them what our specific problems are.What can they do that will ultimately advance ourknowledge of turfgrass managem~nt?

The U niver ity ha men available to do re earchwork in plant di ea es, soil , weed control and rurfgras:management. It would be indeed unfortun.ate. i.f wedo not utilize their talents. I ~ould, as an ll1~lvIdua~,make orne sugge tions to Dr. Blrkelal?d and hIS ~ S~CI-ate. However, a Pre idcnt of. the idwest As ociationit has been and it hall continue to be my duty toexpres the opinions of t.he member. Please makeyour thoughts on thi ubject known to me.

SOIL STERILIZATIONFOR

BETTER TOP DRESSINGby Bill Bengyfield, USGA Western Director

An explorer was once asked, "In the jungle, will thewild beasts harm you if you carry a torch?" - "Itall depends," he answered, "On how fast you carry it."

In today's battle to maintain the best in golfingturf, the golf course superintendent and green chairmansometimes have to run fast just to maintain presentturf conditions. Whether or not they outrun thecompetition and actually bring about turf improvement(or be swallowed by it) depends almost entirely upongood planning, organization and an adequate budget.

Certainly one phase of good putting green managementis an adequate and sensible top-dressing program. Thiswas discussed in detail in the ovember - December1961 We tern T urfletter. ow an important con-ideration (and one receiving an ever increasing

amount of interest throughout the country) in planningthis work is a program of sterilizing or fumigating thesoil mixture. Clean compost soil, free of viable weedseeds, is essential for the top-dressing of green and allfine turf areas including seed beds. Sterilized compo ted. oil, 100 percent weed free, can be produced!

Here are some of the soil sterilants now available.Also included are notes on their use and approximatecost:

M ethyl bromide - is a deadly gas that must beu ed with caution. It is very effective on weeds andnematodes and should be used when temperatures are60 - 65 degrees or above. The rate is 10 to 20 lbs.per 1000 q. ft., and the treated area must be coveredwith an airtight and chemically inert cover (pla tictarpaulin). Leave covered for 48 hour for be t re ult .Planting may be accompli hed two to three day aftercover is removed. Methyl bromide may be purchasedwith a warning agent added (chloropicrin) to reducepos ible accidental inhalation. The co t i 7.50 to$15.00 per 1000 q. ft., add labor and tarpaulin.

J; apam - is a trade name for odium - methyldithiocarbarnate. Other names are ' D and VPM.It give geod control of rno t weed and nematodes.It i usually applied at 2-1/2 gallon per 1000 q. ft.(1 quart per 100 q. ft.) and does be t when applied aa drench. For compo ting, apply at rate of 9 oz. percubic yard of soil. After Vaparn has been applied;irrigate with enouzh water to eal the urfa e to keepthe apam ill the soil. Additional frequent and lightirrigations are very helpful ill keeping the apam inthe oil. At the end of L 4 da s, cultivate the area andallow about two more week. before planting. Approxi-mate co t is $7.50 p r 1000 q. feet.

Calcium Cyanamid - When properly used, thischemical will do an outstanding job of weed controlat a very low cost. I t should be used at the rate of75 to 100 lbs. per 1000 sq. ft. and worked into theupper tW3 or three inches of seed bed. For composting,add 13 lbs. of calcium cyanamid to each cubic yard ofsoil and mix thoroughly. After mixing, irrigate moder-ately if soil is dry. At least four to six weeks areneeded (during warm weather) or eight to twelveweeks (during cool weather) for the calcium cyanamidto break down and bring about weed control. Plantingmust be delayed until after this period. The materialsells for approximately 5¢ a pound.

lIlylone - is a trade name for a chemical known asDMIT. It is effective 0'11 weed seeds and nematodes.It must be applied at the rate of 10 to 12 lbs. per 1000sq. ft., and should be cultivated into the soil or appliedas a soil drench. In composting, mix 2 lbs. to eachcubic yard of soil. Follow the application of Mylonewith an irrigation. A wait of 15 to 20 days is neededbefore planting. Approximate cost is $1.50 per poundfor the material.

Sodium Arsenite - has been used when preparing aseed bed for a green or nursery area. (Note: this isnot suggested for top-dressing preparation). O. J.

oer reports that Poa anriua has been eliminated fromseed beds by spraying sodium arsenite at the rate of1/2 lb. per 1000 sq. feet. Follow by harrowing thetreated area. Repeat this procedure for a total oftwelve times. Allow at least one week before planting.Method to Determine When It Is Safe To Pla.nt Or

Use Sterilized Soil

Because of varying weather conditions, temperaturesand irrigation rates, it is often difficult to determineexactly how soon sterilized soil may be used for top-dressing or planting. A simple test is possible.

Take small random samples of the treated soil andmix them in a pot or flat. Sow radish seeds in thesoil. If the seeds germinate normally in a few days,the soil is ready for use.
